The characteristics of lithium batteries for electric wheelchairs and how to maintain them

Time:2021-11-27 Views:

Lithium electric wheelchairs have gradually entered the electric wheelchair market. At present, most electric wheelchairs on the market still use lead-acid batteries to provide power. With the rise of new energy sources of lithium batteries, the development of the lithium electric wheelchair industry is in full swing. The development and application of lithium batteries are also quite extensive, such as digital 3C, equipment, electric tools, electric bicycles, thinking cars, communication base stations, etc., will be applied to lithium batteries.

     The advantages of lithium batteries relative to lead storage batteries are relatively obvious: high energy density; long service life; high-rate discharge; low self-discharge rate; light weight and small size; strong adaptability and environmental protection. However, the price and cost are relatively more expensive than lead batteries, and the production conditions are also relatively high. However, the increasingly mature production technology, production process, and production cost are well controlled, and it will be more widely used in future application trends.

    There is a difference between the battery maintenance of lithium electric wheelchairs and the maintenance of lead storage batteries:

1. The lithium electric wheelchair battery should be charged with a dedicated charger, and the charger cannot be replaced at will, otherwise it will easily cause damage to the battery.

2. Get in the habit of charging more every day. But it is still necessary to develop the habit of charging every day, so that the battery is in a shallow cycle state, which is good for prolonging the service life of the battery. The lead-acid battery is discharged to about 50%-70% to charge it to maximize the use, and effectively protect the battery.

3. In addition to daily charging, charge as soon as possible after use, and make the battery as full as possible. If the battery is not charged in time, the battery capacity will gradually decrease and the battery life will be shortened.
